Document Type and Number:
WIPO Patent Application WO/2022/179549
Kind Code:
A1
Abstract:
The present invention provides a calibration method and apparatus, a computer device, and a storage medium. The method comprises: obtaining a target image and point cloud data in the same scene; determining a target pixel point of a target object having a linear shape in the target image, and obtaining a target point cloud, in the point cloud data, of the target object having the linear shape, the target object being an element associated with a road; and on the basis of the target pixel point and the target point cloud, determining external parameter calibration information between a photographing device for capturing the target image and a radar for collecting the point cloud data. According to embodiments of the present invention, the target object, having the linear shape, of the road itself is used for external parameter calibration, the calculation amount can be effectively reduced, and the calibration speed and the precision of external parameter calibration are improved.
